' This invention relates to the inking mech- V anism of web printing presses and is a novel ,tool whereby the fountain; screws may be adjusted by the operator from the side of the j press without his having-tof'reach into the press in order to do so. The tool is particularly designed for use in connection with web printing presses of the socalled Cox-O- Type which have two type beds, one above the other and'cylinders' which are reciprocated over the beds, and the web is led from the lower bed up to andover the upper bed. Such presses are provided with ink fountains at the outer end of the pressv adjacent each bed, andthe web in passing from one bed to the other passes around the outer ink fountain of the upper bed; and ordinarily if it becomes necessary to adjust such ink fountain, in case the ink is not properly supplied, it has been necessary to stop the press and break the web opposite the fountain to enable the operator to get. access to the fountain adjusting screws.

The object of my invention is to provide '25 means whereby the operator may adjust the fountain screws without having to stop the press or break the web in order to get at the fountain screws. The invention provides a novel tool whereby the keys of the upper fountain which are located behind the web can be operated from the side of the press. With such toolthe adjusting screws of the upper ink fountain can be operated while the press is running, rendering it unnecessary toand obviating the necessity of of .such fountain.

The tool in brief comprises a spindle hav- 7 ing a square socket in its end to engage the 40 squared end' of any fountain screw. The

outer end of the socket is enlarged to facilitate engaging the spindle with the screw. This spindle may be driven by any suitable means preferably by a bevel gear and pinion,

' and in the construction shown the pinion has a long shaft of hollow light steel tubing which serves as ahandle for operating thetool.

In the accompanying drawings I have illustrated a practical embodiment of the invendrawings, or other the parts are'properly: assembled.-

tion, and willeXp-l'ain the devicewith reference thereto, and summarize in the claims the novel features of construction andcombination of parts for which protection is desired.

In'said drawings:

a i i a Fig. 1 is a top plan view of the tool engaged with a fountain adjusting screw.

Fig. 2 is a side view of the device. Fig. 3 is an inner face view of the rear n casting. 1 a. 6

Fig. 4: is an end view of the tool. [Fig 5 is an enlarged sectional View on the line 5-5 of' Fig. 4. j The tool shown comprises a front member 1, a rear member 2, a screw engagingspindle 4, gears 3 and 5 and an operating handlebar.

The front member is preferably U-shaped in cross sectionand has upper and lower flanges which are'slightly flared I away from each other at each end of the body'l. Thebody l'is provided at center with circular opening 1-b-t0 accommodate the end of the screw engaging spindle 4'. -Thebody is also provided at one end withupper and lower lugs 10. The rear member 2 has a sleeve portion 2a in'axial alinement with the opening and a second sleeve portion 2?) at almost right angles to sleeve 2a and connected therewi h by a curved portion 203. V Sleeve 2?) is provided with lugs 2c, correso sponding to lugs 10, and which may be fastened thereto by bolts, as indicated in the fastenings to securely and rigidly connectthe membersl and2 -when 85 The sleeve 26 is perpendicular to thezaxis also retains the gear'3 in prope'r position.

' Thefront end of'the spindle 4 projects into the opening 1?), and in this end of the spindle is a socket 412 which is adapted to engage the end of a fountain adjusting screw S as indicated in Fig. 1. The ends of the screws S should be angular, and socket 4b similarly angular in cross section so that when the stub shaft is engaged with the end of a screw it cannot rotate thereon, and if the spindle is then turned the screw will be turned. The ends of the screws S are preferably beveled, as indicated ats, and the outer end of'the socket 4b is preferably flared as indicated at 40, to facilitate engagement of the spindle with the end of a screw S;

Rotatably mounted in. the sleeve 2 is a shaft 5a on the inner end of which is fastened a beveled gear 5 which meshes with the gear The shaft 5 should be made long enough tofenable the operator to reach any screw in the length ofthe fountain from the side of the press. The outer end of the shaft 5a may be provided with a crank if desired (not shown) sothat it can be readily turned.

Operation In using the tool the operator holding the handle 5a moves the U-shaped member 1 along the row of screws until it is opposite the screw which he desires to adjust, the U- shaped'body 1 serving to keep the toolin alignment-with the screws as the tool is moved fromaone screw to another. When the=tool is moved opposite the proper screw the'funnel end of the spindle 4 will engage the end .ofthe screw and the spindleis turned until the socket in the spindle aligns with the endof thescrew, then the tool is pressed forward to cause the spindle to slip over the screw as shown'in' Fig. 1. The spindle can then be turned to tighten or loosen thefountain'screwby properly rotating handle 564.,

With this device the-operator can readily control the upper fountain screws or'inner fountain screws of the inking mechanism of a flat bed web press without having to stop the press, break theweb, orhaving to manually reach into the press.

Iclaim: '1. In a tool of 'the'chara'cter specified, a

support-rhaving -flanges adapted to guide and support the tool ontheflfountain screws, a spindle rotatably mounted in said support having a 'socketadapted to engage the end ofa screw, said guide flanges projecting beyond'the end of the'spindle, a handle connected with the support, and means for rotating the spindle.

r 2. An ink fountain adjusting tool' comprising a guide member having opposite flanges adapted to guide and support the tool in engagement with the fountain screws, a spindle rot-atably mounted on said member and having a socket. adapted-to be engaged with a screw, a gear mounted onthe spindle, ahandleconnected with saidmember, anda pinion handle operatively engaging said gear.

4. A fountain screw adjusting, tool comprising; a front member having opposite flanges adapted to guide and support the tool in engagement with the fountain screws and having an opening, a rear member attached to the front member and having a sleeve in alinement with the opening and a second sleeve at an angle to the first sleeve, a spindle jou'rnaled in the sleeve opposite the opening and extending thereinto, said spindle having a-screw engaging socket in its front end,-a.

gear mountedon said spindle, a handle rotatably mounted in the other sleeve, and a pinion mounted on the handle to operatively engage said gear.
